CONNECT TO MY AOKE SMARTWATCH with out their API - CREATE a TXT file from their data - UPLOAD to ftp

I have an academic presentation in a few days for a master's degree graduation and I was thinking about the possibility of creating an app (mobile & android) with no front-end that connects to my own SW vía BT, create a TXT file every x amount of seconds (maybe 300 seconds) and upload that TXT file into a folder via ftp. The SW that Im using is brand AOKE (China) and of course I don't have Aoke API as I'm a student. I was reading from GitLab pages and apparently this is possible to do.
